| Abstract | The burstiness of variable bit rate traac makes it diicult to both eeciently utilize network resources and provide end-to-end network performance guarantees to the traac sources. Generally, smoothing or shaping traac sources at the entrance of the network reduces their burstiness to allow higher utilization within the network. However, this buuering introduces an additional delay so that, in eeect, lossless smoothing trades queueing delay inside the network for smoothing delay at the network edge. In this paper, we consider the net eeect of smoothing on end-to-end performance guarantees where a no-loss, no-delay-violation de-terministic guarantee is provided with the D-BIND traac model. We analytically quantify these tradeoos and provide a set of general rules for determining under which conditions smoothing provides a net gain. We also empirically investigate these tradeoos using traces of MPEG compressed video. |
